Description
BACKGROUND OF THE INVENTION

This invention relates to stabilization of a limb in a patient setting, and in particular to a device for use as an adjunct for limb stabilization.

In co-pending U.S. patent application Ser. No. 11/240,679 filed Sep. 30, 2005 and assigned to the assignee of the present application, a heel ulcer prevention and cushioning boot is disclosed and described. The boot provides heel support and comfort, as well as proper positioning of a patient's leg to avoid creating other problems, such as ulcers.

Sometimes, for whatever reasons, including inability of the patient to maintain proper orientation of a limb, the heel ulcer and cushioning boot may need additional stabilization to maintain the proper limb orientation. The present invention provides that additional stabilization.

SUMMARY OF THE INVENTION

The invention is directed to a device for stabilizing a limb, comprising a stabilization block, a tether secured to and extending from the block, and a fastener for securing the stabilization block in place for supporting the limb.

In accordance with one form of the invention, the stabilization block is elongated and generally triangular in cross-section. The tether comprises an elongated strap, with the fastener comprising a pair of spaced fastener elements on the strap. In one form of the invention, the fastener elements comprise hook-and-loop fasteners which are located substantially at opposite ends of the strap, with one located proximate the block and the other located at the opposite end of the tether.

In another form of the invention, a pair of stabilization blocks is provided, with the blocks being spaced apart and with the tether extending between and secured to the respective blocks.

BRIEF DESCRIPTION OF THE DRAWINGS

The invention is described in greater detail in the following description of examples embodying the best mode of the invention, taken in conjunction with the drawing figures, in which:

FIG. 3 is a perspective view similar to FIG. 1, with the stabilization wedge in place and showing how a patient's leg is supported,

FIG. 4 is a top plan view of the stabilization wedge, and

FIG. 5 is an elevational view of the wedge of FIG. 4.

 DESCRIPTION OF EXAMPLES EMBODYING THE BEST MODE OF THE INVENTION

The stabilization wedge according to the invention is particularly suitable for use in combination with a therapeutic boot, such as the boot 10 illustrated in FIG. 1. The boot 10 is described in greater detail in co-pending U.S. patent application Ser. No. 11/240,679, filed Sep. 30, 2005, the disclosure of which is incorporated herein by reference. Greater detail can be obtained from that application. Of the many features of the boot 10, hook-and-loop fastener segments 12 and 14 are particularly useful in combination with the stabilization wedge of the present invention, as will become evident from the description below.

The stabilization wedge of one form of the invention is shown in FIGS. 2 and 3, with a slightly different form shown in FIGS. 4 and 5. The wedge 20 shown in FIGS. 2 and 3 differs from the wedge 22 shown in FIGS. 4 and 5 only in the particular cross-sectional configuration. As shown in FIG. 3, the wedge 20 is generally trapezoidal in cross-section, while the wedge 22 shown in FIGS. 4 and 5 is generally triangular in cross section. Other shapes of the wedges 20 and 22 will be apparent to one skilled in the art, and the invention is not limited to simply a trapezoidal or triangular cross-section.

No matter the cross-section of the wedge 20 or 22, the wedge comprises a stabilization block, and has a tether secured to and extending from the stabilization block. The tether preferably comprises an elongated strap 24, and may be secured to the respective wedge 20 or 22 by any means, such as sonic welding, adhesives, or any other means of forming a permanent connection between the wedge 20 or 22 and the elongated strap 24. The strap 24 is preferably quite flexible, and can be made of any suitable material, such as plastic or fabric. The wedge 20 or 22, on the other hand, is substantially rigid, and can be formed of any suitable material, such as high density foam, plastic or the like.

As shown in the drawing figures, the wedges 20 and 22 are elongated and for fastening to the boot 10, a fastener is provided in the form of a pair of spaced fastener elements 26 and 28 on the strap 24. The fastener elements 26 and 28 complement the fastener segments 12 and 14, thus one of the segments 12 and 14 or elements 26 and 28 is preferably a hook element, while the other of the fastener segments 12 and 14 and fastener elements 26 and 28 is a loop element. Thus, when the wedge 20 or 22 is applied to the boot 10 as illustrated in the drawing figures, the hook and loop elements engage and hold the wedge 20 or 22 in place.

As illustrated, the fastener elements 26 and 28 are located substantially at opposite ends of the strap 24. The spacing of the fastener elements 26 and 28 is such to advantageously engage the fastener segments 12 and 14. As illustrated, the fastener element 26 is located proximate the stabilization wedge 20 or 22, and the fastener element 28 is located on the elongated strap 24 opposite the fastener element 26.

While the fastener elements 26 and 28 are preferably hook-and-loop fastener segments to advantageously engage the hook-and-loop fastener segments 12 and 14, other types of fastener elements can be employed, as will be evident to one skilled in the art. Permanent fasteners, such as adhesives, can be utilized, as well as other types of temporary connection to the boot, such as various kinds of fasteners. The type of connection will be dictated by whether the user wishes a more permanent type of connection, or a readily removable type of connection.

As is evident, the stabilization wedge 20 or 22 can be used on either side of the boot 10. If need be, the wedges 20 or 22 can be doubled, that is, instead of a single wedge proximate the fastener element 26, there can be a second wedge, such as the wedge 22′, proximate the fastener element 28. Thus, both sides of the boot 10 can be stabilized if needed.

The shape of the wedge 20 or 22 can vary depending upon the nature of the boot 10 and the use in connection with the boot. While two types of wedges 20 and 22 have been illustrated and described, it will be evident that other shapes will perform the stabilization functions as explained.

Various changes can be made to the invention without departing from the spirit thereof or scope of the following claims.
